MACHINE FOR FILLING VALVE-BAGS.

Specification of Letters Patent.

PatentedNov.19, 1912.

Application filed May 10, 1909. Serial No. 495,182.

To all whom it may concern:

Be it known that I, Annmrnn M. Buns, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Machines for Filling Valve-Bags, of which the following is a specification.

My invention relates to machines for filling bags and has for its object to provide new and improved constructions in machines of that class.

The invention relates more particularly to machines for filling valve bags or other rece tacles which have to be filled through a re atively small opening, and contemplates an arrangement for suspending the bags upon filling tubes, which tubes, together with the bags, are connected with scales to measure theproper amount of material.

My invention also contem lates supporting the bag from the top a one instead ofgiving it the ordinary support at the. bottom, although the bags might 'be so supported and jigged if necessary if the character of the material of whichthe bags are made or if the material with which they are to be filled should make such a support expedient. I alsijoin the two ideas of paritially supporting tie bag from the top by means of the tube and supporting it. either all or part of the time by means of the jigging device from the bottom.

My invention has also for its object such further improvements and novel devices as are shown and described in the specification.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation and part sectional view of my invention showing the bag supported on the scale; Fig. 2 is a similar view showing the adjustable jigging device to support the bag from the bottom.

Like numbers indicate like parts throughout the drawings.

1 is a hopper or bin containing the material with which the bags are to be filled, this hopper terminating preferably in a cylin- "drical feeding chamber 2 in which revolves The bag is supported at the top by a filling tube 7, which extends through its filling opening, and preferably on the sides and back of the cradle 8. The filling tube normally alincs with discharge openings 5, being hcld against a block 9 on the outside of th' filling chamber by the operation of the scale which will be described later. The filling tube is connected with a swinging frame work consisting of two uprigl'its 10, 10. The inner end of the filling tube is attached to a bracket 14 extendin from one of the up rights and it projectmgfrom the bottom of the case 11. The cradle is connected with the filling tube by means of theibracket 15. The uprights 10 are riveted to the side of the cradle, It is also associated with some form of weighing apparatus so' that the filling tube Wlll. be held in alinement with the discharge 0 ening of the filling chamber during the lling operation and will be free to move away from the same when the required quantity of material has been inserted 1n overcome by the weight ofthe material in l the bag.

The scale beams 18 have each a grooved block 45 supported on the knife edge 46. The weightlt) is hung from a threaded bolt 47 and held in adjustment by nuts 48, 48.

It is import-ant that the vertically movable frame should be held from lateral motion and the filling tubes accurately guided into position in alinement with the discharge opening of the feed chamber. This I accomplish by means of the double scale beam with its engagement with the cradle on each side.

In the mouth of the feed hopper is preferably an agitator consisting of a shaft 50 on which are propeller blades {31.

The bag may be held upon the filling tube 7 in any desired manner. For example, I have shown a clip 52 which is pressed against the material of the bag by the cam 58 pivoted ina fork 54 on the diagonal brace 14 and provided with a handle 55.

The jigging device 'serves on occasion to jig or shake the bag, is' set out in Fig. 2 wherein 56 is the jigging board and having the dou'nuardly depending jigging bar 57 in the sleeve 58, "which is mounted on the reel: lever 59 fulcrumed on the =-standard G0. The outer end of thislever has the link ()1 on the t-readle (32, which is'fnlcrumed at- 63. Associated with the lower end of the sleeve 58 the shaft M, driven by the belt. 65 and carrying the eccentric (3G adapted to operate against the lower end of the bar 57 to oscillate the parts. The operation of the treadle tilts the lever 59 and raises the. jigging device so as to bring it into operatiie relation to the bag above.

It will be understood that these struc- .tures, and particularly those of Fig, 2, are

largely' diagrammatic.

I do not desire to be limited tothe exaet details of construction shown 'or described for obvious modifications will occur to any person skilled in the art and ponsiderable change can he made without departing from the spirit of my invention. 7 i

In my claims I shall pointout what I specially desire to cover.

The use and -operation of my invention are ps 'follows: Iteferringto the jigging app ra it is enough to say ..t-hat it 15 arranged so as to be, at the will of the operator, in or out of operation.

or shake it, as the supplied through tie filling tube will be sufficient to thoroughly till the bag. The bag is shown as without a bottom support except when the jigging table is'brought into In many for i cases it will not be necessary to jig the ba 'ressure ofthe materiad gi g bag would be p art-ially supported from I; above and partially from below.

Looking at the filling tubegwefffind that it is a separable filling tube; that it is a movable tube in the sense that itlmoves with relation to the part from whichflit' is sup plied. It is capable, thereforq'iof{disassoct ation with reference tothe feeding appa ratus.

I claim:

1. In a 'bag fillingmaehine"the'combinw 1 tion with a ling tube adapted to cngagi thebag at its top, of means-for supporting the bag at the bOttOD1,'S1-Id means including a jiggin device and'means 'for interniit tently brlnging said supporting means into operative engagement with: the bag independent of the jigging action. f 2. In a bag filling machine the combination of supporting means intermittently op erative at both top and bottom of the bag.

the bottom supporting means comprising a jigging device. v

3.'In a bag filling ma hine, bag jigging meehanismcomprising a lever, an eccentric 'roller carried by said lever, means'for no tating said roller, 21 jigging rod in contact with said eccentric roll 1;, a ig'board car ried by said rod, means 'for operating-said lever about a fixed point to bring it into opposition to the bottom of the bag.
